Objective To observe the effects of rehabilitation in the 55 prelingually deaf pediatric cases for two years after cochlear implantation ,factors including cochlear implantation and recovery time ;to compare the re-covery effects in the group of 1 to 3 years old children with the group of 3~5 years old (including the age of 3 years old) who lost their hearing before learning to speak ,and to provide clinical evidence for providing cochlear implant therapy to the prelingually deaf children as early as possible .Methods A total of 55 pediatric relingually deaf cases were included in this study .According to their implantation time and application duration ,they were divided into 2 groups :1 to 3 years old group (32 cases) ,and >3 to 5 years old group (23 cases) respectively .The hearing ,lan-guage and learning abilities on 1 ,3 ,6 ,12 ,18 ,24 months after cochlear implantation were evaluated ,using statisti-cal method to record CAP and SIR scores .Results The rehabilitation effects ,the average ages ,CAP ,speech rec-ognition rates and SIR were increased two years afterwards .The effects of younger age group were more noticeable than that in the older group .The differences between the two groups were statistically significant (P<0 .05) .Av-erage speech recognition rates ,average speech rehabilitation effects in each postoperative period of younger age group were better than those of in older age group ,showing significant differences (P<0 .05);CAPs in the younger age group on 1 ,3 and 12 months after CI surgery were significantly higher than those of in the older group (P value were 0 .001 ,0 .001 and 0 .002 ,respectively) .SIR in the younger age group at the time of 1 ,3 ,12 ,24 months were significantly higher than those of in the older group(P values were 0 .00 ,0 .00 ,0 .00 and 0 .024 ,respectively) . Conclusion Implanted age and recovery time are the key factors that influence the effects of postoperative rehabilita-tion .The younger when the children get cochlear implantation and the longer the recovery time takes during two years after cochlear implantation ,the better the results are .The standardization of domestic assessment for the re-covery effects and the international evaluation method have a certain degree of equivalence .

Objective To study the drug resistance of infection bacteria deriving from acute appendicitis patients.Methods The separation and the drug sensitive characteristic of bacteria deriving from the specimen of acute appendicitis patients were ana-lyzed,who were admitted in the general department of our hospital from January to June 2013.Results One hundred and six bacte-ria strains were isolated.Among them,100 (94.34%)strains were Gram negative bacteria strains,including escherichia coli,kleb-siella pneumonia bacillus and verdigris fake single spore bacterium,in a proportion of 67.92%,1 1.32% and 5.66% respectively. The resistance of piperacillin,ciprofloxacin,gentamycin,levofloxacin,tobramycin and cefepime was high in Gram negative bacteria, while the lower resistance to piperacillin/ tazobactam,cefoxitin and imipenem.Conclusion The resistant rate of acute appendicitis infection bacteria is high.

Objective To evaluate the relationship between genetic polymorphism of transforming growth factor (TGF)-β1 and susceptibility of liver cirrhosis after hepatitis B virus infection in Chinese population. Methods CBM, VIP, CNKI, Wanfang technological periodical full-text databases and Pubmed from set up to July, 2013 were electronically searched to identify case-control studies on the relationship between genetic polymorphism of TGF-β1 promoter 509 site, co-don 869 site and liver cirrhosis after hepatitis B virus infection. The data were quantitatively analyzed by RevMan 5.1 soft-ware after assessing the quality of included studies. Results Six case-control studies were selected for Meta-analysis based on our inclusion and exclusion standards. The results of Meta-analysis showed that the pooled OR value for liver cir-rhosis among Chinese patients after hepatitis B virus infection with T allele of TGF-β1 gene at promoter 509 was 1.02 (95%CI:0.67-1.54), the pooled OR values for patients with TT and CT genotypes were 0.80 (95%CI:0.36-1.78). OR values for pa-tients with C allele of TGF-β1 gene at codon 869 was 1.05 (95%CI:0.69-1.62), the pooled OR values for patients with CC and CT genotypes were 0.98 (95%CI:0.48-2.00). No significant publication bias was found. Conclusion The genetic poly-morphism of TGF-β1 at promoter 509 and codon 869 showed no association with susceptibility of liver cirrhosis after hepati-tis B virus infection in Chinese population.

OBJECTIVE:To investigate the role of clinical pharmacists in the anti-infection treatment for gas gangrene chil-dren. METHODS:Clinical pharmacists participated in the anti-infection treatment of a child with gas gangrene;according to clini-cal symptoms and consultation opinions of different departments,it was suggested to use Piperacillin sodium and tazobactam sodi-um for injection for initial anti-infection treatment. After debridement and drainage of left lower limb,removal of necrotic tissue, clinical pharmacists suggested to stop giving Piperacillin sodium and tazobactam sodium for injection and use Benzylpenicillin sodi-um for injection combined with Imipenem and cilastatin sodium for injection instead for anti-infection treatment according to etiolog-ical characteristic of gas gangrene and related guidelines. According to the results of bacterial culture of wound secretion and drug sensitivity test,clinical pharmacists additionally suggested to use Clindamycin hydrochloride and sodium chloride injection 0.6 g, q8 h,ivgtt to inhibit the generation of Clostridium perfringens.According to the changes of patient's signs and etiological results, it was suggested to stop taking Clindamycin hydrochloride and sodium chloride injection,use Vancomycin hydrochloride for injec-tion successively. RESULTS:The physicians adopted the suggestions of clinical pharmacists.After surgical treatment and anti-infec-tion treatment,the patient's condition was improved,the vital signs were stable,and the patient was transferred to the general ward of orthopedics department for further treatment. CONCLUSIONS:Clinical pharmacists participate in the treatment of gas gan-grene child,and assist physicians to formulate and adjust anti-infection treatment plan according to related guidelines,clinical symp-toms,etiological examination results and consultation opinions,so as to guarantee safe and effective drug use.

According to the pathological characteristics of symptomatic chronic thoracic and lumbar osteoporotic vertebral fracture (SCOVF), the different clinical treatment methods are selected, including vertebral augmentation, anterior-posterior fixation and fusion, posterior decompression fixation and fusion, and posterior correction osteotomy. However, there is still a lack of a unified understanding on how to choose appropriate treatment method for SCOVF. In order to reflect the new treatment concept and the evidence-based medicine progress of SCOVF in a timely manner and standardize its treatment, the clinical guideline for surgical treatment of SCOVF is formulated in compliance with the principle of scientificity, practicability and advancement and based on the level of evidence-based medicine.
